Subject: [PATCH] Add validate.yml PR workflow for changed ckans

- Mirror KSP-CKAN/KSP2-CKAN-meta's validate.yml: run the xKAN-meta_testing action (game KSA, source commits) on pushes to main and on PRs, with the download cache step.
- Runs fail until KSA client support is merged into upstream KSP-CKAN/CKAN, because the action executes the upstream-built kspckan/metadata image, which rejects --game KSA until then.

Closes #4
